Schema Validation by Directory Proxy Server

Directory Proxy Server provides schema validation to ensure that only the allowed data
is permitted on write operations. For example, when entries are aggregated using the
virtual directory functionality, the aggregate entries might not match the schema of any
of the backend servers participating in the entry aggregation. In this case, schema
checking can occur on the Directory Proxy Server using a virtual schema.

When schema checking is enabled, Directory Proxy Server retrieves schema available in the
cn=schema suffix and uses it to do schema checking. You can define the
LDIF data view holding the cn=schema suffix. The content of the cn=schema suffix
can point to an LDAP server or to a schema stored in an
LDIF file local to the Directory Proxy Server.
